Mobile terminal device

Abstract

A mobile terminal device includes a display control module 100 performing display control on display modules 11 and 21 and a setting module 100 setting an icon to be kept secret according to a setting operation. In this arrangement, the display control module 100 performs control such that the secret icon set by the setting module 100 is not included in an icon display screen.

The invention claimed is: 
     
       1. A mobile terminal device comprising:
 a display configured to display an icon display screen including one or more icons; 
 an operation accepting module configured to accept an operation input; 
 a setting module configured to set at least one icon to be kept secret according to a setting operation; 
 a display control module configured to control the display such that, in a first mode, the at least one secret icon set by the setting module is not included in an icon display screen, and, in a second mode, the at least one secret icon set by the setting module is included in the icon display screen; 
 a memory module configured to register an operation input as the permission operation which permits the second mode; and 
 a detection module configured to detect the permission operation based on a comparison of the registered operation input with an operation input accepted by the operation accepting module; 
 wherein, when the display is in the first mode and the permission operation is detected by the detection module, the display control module switches the display to the second mode such that the secret icon is included in the icon display screen, and, 
 wherein, when displaying of an operation screen of an application corresponding to the secret icon is stopped and then the icon display screen is displayed on the display without detection of the permission operation, the display control module controls the display such that the icon display screen does not include the secret icon. 
 
     
     
       2. The mobile terminal device according to  claim 1 , further comprising a touch panel,
 wherein the permission operation comprises a figure drawn on the touch panel. 
 
     
     
       3. The mobile terminal device according to  claim 1 ,
 wherein the display comprises a first display disposed at a first cabinet and a second display disposed at a second cabinet, wherein the first and second cabinets are configured to switch between a closed state in which the first cabinet and the second cabinet are overlapped each other and an open state in which the first cabinet and the second cabinet align horizontally, and wherein, when the permission operation is detected while the first and second cabinets are in the closed state and then the first and second cabinets are switched to the open state, the display control module switches the display to the second mode such that the secret icon is included on the icon display screen displayed on one or both of the first display and the second display. 
 
     
     
       4. The mobile terminal device according to  claim 3 ,
 wherein, when the first and second cabinets are in the open state, a secret application corresponding to the secret icon is under execution, an operation screen for the secret application is displayed, and then the first and second cabinets are switched to the closed state, the secret application continues to be executed but the display control module stops displaying the operation screen for the executing secret application. 
 
     
     
       5. The mobile terminal device according to  claim 4 ,
 wherein, when the permission operation is detected while the first and second cabinets are in the closed state after stoppage of display of the operation screen and then the first and second cabinets are switched to the open state, the display control module displays again the operation screen for the secret application. 
 
     
     
       6. The mobile terminal device according to  claim 4 ,
 wherein, when the permission operation is not detected while the first and second cabinets are in the closed state after stoppage of display of the operation screen and then the first and second cabinets are switched to the open state, the display control module does not display the operation screen for the secret application. 
 
     
     
       7. The mobile terminal device according to  claim 3 ,
 wherein, after the permission operation is detected by the detection module while the first and second cabinets are in the closed state, when the first and second cabinets are not switched to the open state within a predetermined time limit, the display control module invalidates the permission operation. 
 
     
     
       8. The mobile terminal device according to  claim 3 ,
 wherein the permission operation is accepted when the operation input is performed to the first display while the first and second cabinets are in the closed state. 
 
     
     
       9. The mobile terminal device according to  claim 8 ,
 wherein the operation accepting module comprises a touch sensor arranged on the first display.
